Answer:
Carbons 1 and 3
Explanation:
We must remember that by definition <u>alpha carbon</u>s are the carbon (or carbons) next to the carbon that contains the main group. In this case, the main group is the carbonyl group (C = O) in the middle of the molecule. In the acetone molecule, we have three carbons, the carbons neighboring the carbon of the carbonyl group (carbon two) will be the <u>alpha carbons</u>. (Red and blue carbons or carbons one and three)
See figure 1 for further explanations.

Answer:
The number of atoms in 1 mole silver is also 6.022 *10^23 atoms.
Option C is correct.
Explanation:
Step 1: Data given
Mass of 1 mole silver = 107.9 grams
Step 2: Calculate the number of atoms in 1 mole of silver
To calculate the number of atoms in 1 mole, we multiply the number of Avogadro by the number of moles
Number of atoms = 1 mol * 6.022 *10^23 atoms/ mol
Number of atoms = 6.022 * 10^23 atoms
Since the number of Avogadro says there are 6.022 * 10^23 atoms per 1 mole. The number of atoms in 1 mole silver is also 6.022 *10^23 atoms.
Option C is correct.
Answer:slowly
Explanation: when a gas is being cooled then its particles are gonna slowly stop moving to form a liquid
Answer:
See below
Explanation:
The way to calculate this
speed of light = wavelength * frequency
3 x 10 ^8 m/s = wavelength * 2450000000 Hz
wavelength = .12245 meters
= 1.2245 x 10^-1 Meters
Answer:
185.92 L
Explanation:
Given data:
1 mole = 6.022× 10²³ molecules
1 mole = 22.4 L
Volume occupy by 5.0× 10²⁴ molecules
Solution:
1 mole = 6.022× 10²³ molecules
5.0× 10²⁴ molecules × 1 mole / 6.022× 10²³ molecules
0.83× 10¹ mol
8.3 moles
1 mole occupy 22.4 L
8.3 mol × 22.4 L / 1 mol
185.92 L
